摘要:

含碳耐火材料具有優良的熱震穩定性和抗渣侵蝕性，廣泛應用于堿性氧氣轉爐、電弧爐、鋼包、滑板、連鑄“三大件”等鋼鐵冶金設備。為滿足鋼鐵冶金節能環保、潔凈鋼冶煉等新生產技術的要求，低碳耐火材料甚至超低碳耐火材料的發展具有重要意義。然而，直接減少鱗片石墨在傳統含碳耐火材料中的添加量，會導致材料韌性降低、惡化其抗熱震性及抗渣侵蝕性能。近年來國內外研究人員已經開始將納米碳源引入到低碳耐火材料中，在降低耐火材料中碳含量的同時，優化材料的性能。但是，納米碳存在制備工藝復雜、成本高、易團聚、易氧化等問題，限制了其在含碳耐火材料中的工業應用。概述了國內外研究人員關于不同類型的納米碳對低碳耐火材料各方面性能的影響研究，各類型納米碳引入低碳耐火材料需要解決的問題，以及在降低碳含量、提高低碳耐火材料使用性能方面的進展情況。

Abstract:

Carbon containing refractories have been widely used in steel ladles, arc furnaces, basic converters, slide plates, and functional refractories for con-casting, benefiting from their high resistance to corrosion, slag penetration, and thermal shock. It is urgent to develop low-carbon refractories and ultra-low-carbon refractories in response to “low carbon economy” environment all over the world and the requirement to develop clean steel. However, decreasing the content of graphite flake in the traditional carbon containing refractories can decrease the toughness and deteriorate the thermal shock and slag corrosion resistance. Researchers have pointed out that nano carbons have shown their capability in decreasing the total carbon content while improving or maintaining the comprehensive properties. However, the application of nano carbons as carbon source is limited because of their high cost, poor dispersibility and vulnerable to oxidation. In the present work, the research progress of the influence of different types of nano carbons on the performance and potential problems of low carbon refractories is overviewed.
